Record 4 2001-02-15

English

Subject field(s)
  • Aircraft Propulsion Systems
CONT

The fuel-oil heater serves a twofold purpose, it is designed to cool the oil and preheat the fuel for combustion.

CONT

Bell 212 helicopter... Engine power loss. Engine tear-down inspections revealed that the number two engine was not operating on impact and the fuel oil heater had malfunctioned, however this malfunction alone would not cause the engine to stop operating. If fuel pressure upstream from the engine driven boost pump is lost when the fuel oil heater has malfunctioned(allowing the fuel to be heated), the engine will stop operating. Since the investigation revealed no other reason for the engine to stop operating, it is likely that the number two engine shut down due to a loss of line fuel pressure provided by the electrical boost pumps, coincident with the malfunctioning fuel oil heater.

Record 5 1990-10-05

English

Subject field(s)
  • Burners and Steamfitting
  • Gas and Oil Heating
CONT

Domestic burners... employ either one of two methods to prepare the fuel oil for combustion. These are atomization(spraying) and vaporization(heating). Atomization or spraying is divided into three types, namely, high-pressure atomization, low-pressure atomization, and centrifugal atomization. With high-pressure atomization used by high-pressure gun-type burners, the oil pressure is built up to 100 psi by a pump and delivered through an oil line to a specially designed nozzle from which it sprays out into the combustion chamber in a vaporous cloud of tiny globules or droplets. This mist of fine oil droplets is met by a current of air moving down the blast(gun) tube, and the oil and air mix in the combustion chamber after leaving the burner. Ignition is accomplished with an electric spark.

French

Domaine(s)
  • Fumisterie et brûleurs
  • Chauffage au gaz et au mazout
CONT

Pulvérisation par l'air sous haute pression. Les brûleurs qui sont étudiées pour l'utilisation de l'air sous haute pression, donnent une pulvérisation très fine qui se traduit par une combustion rapide particulièrement appréciée pour les applications qui demandent une extrême localisation de la chaleur.

Record 6 1990-10-05

English

Subject field(s)
  • Burners and Steamfitting
CONT

... the functional parts of a typical nozzle.... The flow rate, spray angle, and pattern are directly related to the design of the tangential slots swirl chamber and orifice. In operation, a source of energy is needed to break up the oil into small droplets. Therefore, pressure is supplied to the nozzle from the oil pump.... However, pressure energy alone is not enough to do the job. It must be converted to velocity energy. This is accomplished by directing the pressurized fuel through a set of slots. These slots are cut in the distributor at an angle, or tangentially, to produce a high velocity rotation within the swirl chamber. At this point, about half of the pressure energy is converted to velocity energy.

French

Domaine(s)
  • Fumisterie et brûleurs
CONT

Dans le brûleur à pulvérisation par pression d'huile, le combustible est injecté sous pression par l'intermédiaire de canaux tangentiels dans une chambre de rotation aboutissant à la sortie du gicleur : le combustible s'étale alors dans un cône d'expansion et est pulvérisé par l'action d'un courant d'air engendré par un ventilateur.
